New classes of exact solutions to general nonlinear equations and systems of equations in mathematical physics. (English) Zbl 1217.35166

From the text: New classes of exact solutions to some general nonlinear equations and systems of equations of mathematical physics are described that involve arbitrary functions. Special attention is given to equations and systems of equations encountered in the theory of mass and heat transfer, mathematical biology, and wave theory.

In this paper, an exact solution is regarded in the sense of the definition given in [A. D. Polyanin, V. F. Zaitsev and A. I. Zhurov, Methods for solving nonlinear equations in mathematical physics and mechanics. Fizmatlit, Mowcow, (2005)], page 10.
